I am a joint postdoc at UC Berkeley & Caltech, working with Prof. Jennifer Chayes, Prof. Christian Borgs, and Prof. Anima Anandkumar.

I got my CS Ph.D. degree with at Quebec Artificial Intelligence Institute (AKA Mila) and Université de Montréal, advised by Prof. Jian Tang. Meanwhile, I have close collaboration with Prof. Hongyu Guo.

I got my CS master’s degree from University of Wisconsin-Madison, and was the graduate researcher at Morgridge Institute for Research. During my stay in UW-Madison, I started my first research project and was fortunately advised by Prof. Anthony Gitter, Prof. Yingyu Liang, and Prof. Dimitris Papailiopoulos. Proir to that, I got my bachelor’s degree from Shandong University.

I also want to share some inspiring research values (special thanks to Weiyang)

• Focus on creating novel ideas, not publishing papers
• Follow curiosity and passion, not trends
• Ideas are not owned, but come with debts to those who came before
• Ideas become stronger when shared, discussed and criticized
• Life is surprisingly short, so solve problems that interest and excite you most
• It is good to be quick, but it is more important to be deep
• Think like an amateur, do as an expert
• Last lecture by Prof. Randy Pausch
• [My own words] Hope you can know me through my work ;)

Interests

• Coding. Like ACM-ICPC and Capture the Flag.
• Video Editing. Quite cool stuff.
• Reading. Novels are my favourite, but also history and computer books.
• Music. Classical music are perfect match for coding.
